Alexandria police have turned to the public for help tracking down a gun-wielding man who robbed the 4653 Duke Street Dunkin Donuts late on Thursday morning.

Authorities describe the suspect as a thin black man in his mid-20s and about 5-foot-10. A store surveillance camera captured the man walking into the coffee shop at 11:15 a.m. He drew a handgun, police said, and demanded cash.

After an employee turned over the register’s contents, the man left the store. He was last seen in a small, blue vehicle heading westbound on Duke Street. Officials did not release the amount of cash stolen in the daylight heist.

The robber wore khaki pants and a white plaid shirt during the holdup. Footage of the robbery is available online at www.youtube.com/alexandriavapd. Police urge anyone with information about the suspect or the incident to contact detective Chris Whelan at 703-746-6884.
